Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a cell load adjustment method and a cell load adjustment device.
Background
In the background of rapid development of 4G technology (fourth generation mobile communication technology), collaborative networking and convergence have developed into a hot topic for industry discussion. From the current situation, LTE (Long Term Evolution) collaborative networking is a trend, and for operators, it is also beneficial to balance the competitive pattern of 4G development. The LTE cooperative networking refers to cooperation between TDD (Time Division duplex) and FDD (Frequency Division duplex), so that advantages of TDD and FDD are complementary, network resources are shared as a whole, and fusion is achieved in the network, service and Frequency layers, thereby saving deployment cost.
The TDD/FDD cooperative networking can utilize the similarity of two 4G systems, fully exert the advantages of the two systems, enhance the continuous coverage of a service hot spot area T + F, optimize and adjust network parameters, increase the construction and development strength, improve the utilization rate of LTE and realize the integration of TDD and FDD mobility management. In capacity fusion management, Load Balancing (Load Balancing) is a key point of cooperative networking. When the load is unbalanced due to the outbreak of the flow in the cell, the terminals with the over-sized load area are transferred to other cells through the load difference threshold which is set based on the load target service and reasonably set, so that the multi-band balanced distribution service load of one network is realized, and the maximum utilization rate of resources is reached.
The existing load balancing decision scheme is carried out based on the number of users, when the number of users in a cell reaches a certain threshold, a system triggers a load balancing process, and the users can be migrated from a system with high load to a system with light load. The conditions for its decision are as follows:
1) the user number balance switch is turned on;
2) the same coverage adjacent cell and the same coverage adjacent cell are in a non-high load state;
3) the number of the local area connection users is larger than the set user number balance threshold, the number of the local area connection users is larger than the number of the neighboring area connection users, and the ratio of the difference value of the number of the local area users and the number of the neighboring area users to the number of the local area users is larger than or equal to the set user number difference threshold.
However, since all users in the LTE system can share resources, the actual measurement of the number of users cannot truly reflect the actual load level occupied by the radio resources. For example, when there are only a few users in a cell, but all of them are large-rate FTP (file transfer Protocol) type services, since the data volume of the services is large, bandwidth resources of the whole cell may be occupied, and if a decision is made according to the number of users at this time, many users may still be actually admitted, but QoS (Quality of Service) requirements of all users cannot be guaranteed.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
Referring to fig. 1, a flowchart illustrating a first step of a first embodiment of a method for adjusting a cell load according to the present application is shown, which may specifically include the following steps:
in this embodiment of the present application, the number of the first physical resource blocks PRB may be a value that can reflect an actual load level of the system by converting a measured resource occupied by the current cell into a value according to a certain calculation method. Further, the number of the first physical resource blocks PRB may be obtained by calculating a sum of resources occupied by all access users of the current cell.
Generally, the number of first physical resource blocks PRB may be calculated by a MAC (Media Access Control), and then reported to a High layer (High lys) by the MAC. Therefore, the higher layer can receive the information of the number of the first physical resource blocks PRB of the current cell in time.
In a preferred embodiment of the present application, the number of first physical resource blocks PRB may be obtained through the following steps:
s11, traversing users of the current cell;
s12, calculating the number of PRBs (physical resource blocks) of each user;
in specific implementation, all accessed users of the current cell can be obtained, and physical resource block PRB resources occupied by each user are respectively counted, so that the number of second physical resource blocks PRB of each user is obtained. The number of the second physical resource blocks PRB may be an equivalent value obtained by converting the measured resource occupied by the current user according to a certain calculation method.
Generally, in the 4G era, a user can simultaneously perform a plurality of business operations. For example, after the 4G voice function VoLte is implemented, the user can make a call while surfing the internet. However, each bearer can only correspond to one service, and thus, a user needs to establish two bearers, one for internet access and the other for voice communication. Therefore, each user may have one or more service bearers, and in a specific implementation, the following formula may be adopted to calculate the number of second physical resource blocks PRB for each user:
wherein, RBnumberiActual number of physical resource blocks PRB occupied for ith service bearer, RBSpeediRBQoS being the actual rate of the ith traffic beareriThe minimum guaranteed rate of the ith service bearer is obtained, and n is the total number of the service bearers of the current user.
Further, the traffic may be divided into GBR (Guaranteed Bit Rate) traffic and non-GBR traffic. GBR means the minimum bit rate of the bearer guaranteed by the system, and even under the condition of network resource shortage, the corresponding bit rate can be maintained; on the contrary, non-GBR means that in case of network congestion, the traffic needs to bear the requirement of reducing the rate, and the non-GBR bearer can be established for a long time because it does not need to occupy fixed network resources, while the GBR bearer is generally established only when needed.
For GBR traffic, its QoS requirements can be determined according to 3GPP (3rd Generation Partnership Project) definitions. For the non-GBR service, the QoS requirement may be a minimum guaranteed rate of the non-GBR that is considered by the user, and for different service types, the minimum guaranteed rate of the non-GBR may be configured by the operator according to actual requirements.
And S13, accumulating the number of the second physical resource blocks PRB of each user to obtain the number of the first physical resource blocks PRB.
After the number of the second physical resource blocks PRB of all the access users of the current cell is obtained, the number of the first physical resource blocks PRB of the current cell can be calculated by accumulating the number of the second physical resource blocks PRB of each user.
generally, the occupation condition of the PRB resources is an instantaneous value reported in seconds, and for different service types or in different time periods, there may be large fluctuation, so that after receiving the number of the first physical resource block PRB of the current cell, the higher layer may also perform smoothing processing on the number of the first physical resource block PRB, that is, the number after smoothing processing is obtained by recording the current actual stored value in the historical stored value according to a certain proportion, and the physical resource block PRB utilization ratio of the current cell is calculated according to the smoothed value and the actual available physical resource block PRB number of the current cell.
And 103, adjusting the load of the current cell according to the physical resource block PRB utilization rate.
In specific implementation, after calculating the physical resource block PRB utilization rate of the current cell, it may be determined whether the utilization rate exceeds a preset threshold, and if so, the physical resource block PRB utilization rate may be reduced in a manner of migrating a user of the current cell to an adjacent cell, so as to adjust the load of the current cell and implement load balancing.
In the embodiment of the application, the number of PRBs (physical resource blocks) of the current cell is received, and the utilization rate of the PRBs of the current cell is calculated according to the number of the PRBs of the first physical resource block, so that the load of the current cell is adjusted, the problem that the QoS (quality of service) requirements of all users can not be guaranteed due to the fact that the network condition can only be judged according to the number of users in the prior art is solved, the terminals of the cells with the too large and small loads can be transferred to other cells according to the actual use condition of the resources, the one-network multi-band balanced distribution service bearing is realized, the maximum utilization efficiency of the resources is achieved, and the user satisfaction is favorably improved.
Referring to fig. 2, a flowchart illustrating steps of a second embodiment of the cell load adjustment method according to the present application is shown, and specifically, the method may include the following steps:
generally, after calculating the number of first physical resource blocks PRB of a current cell, the MAC reports the number of first physical resource blocks PRB to a higher layer at a certain period (for example, 1 s). Therefore, in the embodiments of the present application. And the high layer can also receive the information of the number of PRBs of the first physical resource block of the current cell according to a preset period.
In a preferred embodiment of the present application, the number of the second physical resource blocks PRB of each user of the current cell may be calculated by using the following formula, and then the number of the second physical resource blocks PRB of each user is accumulated to obtain the number of the first physical resource blocks PRB.
Wherein, RBnumberiActual number of physical resource blocks PRB occupied for ith service bearer, RBSpeediRBQoS being the actual rate of the ith traffic beareriThe minimum guaranteed rate of the ith service bearer is obtained, and n is the total number of the service bearers of the current user.
In a specific implementation, the MAC may respectively calculate the number of the uplink first physical resource blocks PRB and the number of the downlink first physical resource blocks PRB, and respectively report the uplink data and the downlink data to a higher layer.
For non-GBR traffic, the uplink QoS Rate may be calculated in PBR, and the downlink QoS Rate may be calculated in MinBR (minimum bit Rate); for GBR traffic, the QoS Rate corresponds to a guaranteed Rate of GBR, and GBR (maximum Bit Rate) may be configured, that is, the number of PRBs in the first physical resource block of the GBR traffic is considered to be equal to the number of actually scheduled PRBs.
generally, the occupation condition of the PRB resources is an instantaneous value reported in seconds, and for different service types or in different time periods, there may be large fluctuation, so that after receiving the number of PRBs in the first physical resource block of the current cell, the higher layer may also perform smoothing processing on the number of PRBs in the first physical resource block, that is, the number is obtained by calculating the current actual stored value in the historical stored value according to a certain ratio, so as to obtain a smoothed value.
In a preferred embodiment of the present application, the step of smoothing the number of the first physical resource blocks PRB to obtain a smoothed number of third physical resource blocks PRB may specifically include the following sub-steps:
substep 2021, obtaining the number of first physical resource blocks PRB in the current period and the previous period respectively;
and a substep 2022, performing weighted summation on the number of the first physical resource blocks PRB in the current period and the previous period to obtain the number of the third physical resource blocks PRB.
In specific implementation, the number of first physical resource blocks PRB stored in the previous period by the high layer and the number of first physical resource blocks PRB actually received in the current period may be obtained, and a smoothing factor is used to perform weighted summation, so as to obtain the number of third physical resource blocks PRB, where the number of third physical resource blocks PRB is a value obtained after the number of first physical resource blocks PRB is smoothed.
As an example, in the embodiment of the present application, a smoothing factor (3/4,1/4) may be used to calculate the number of the third physical resource blocks PRB, that is, the number of the third physical resource blocks PRB is 3/4 × the number of the first physical resource blocks PRB of the previous cycle +1/4 × the number of the first physical resource blocks PRB of the current cycle. Those skilled in the art can adjust the smoothing factor by modifying the memory according to actual needs, which is not specifically limited in this application.
In a preferred embodiment of the present application, the smoothing processing on the number of first physical resource blocks PRB may also be calculated according to the number of uplink first physical resource blocks PRB and the number of downlink first physical resource blocks PRB, respectively.
in the embodiment of the application, the physical resource block PRB utilization rate can be obtained by dividing the number of the third physical resource block PRB by the number of the available physical resource blocks PRB of the current cell.
In a specific implementation, if the number of PRBs reported by the MAC is performed according to a 1s cycle, the current cell downlink physical resource block PRB utilization rate is 100% of the number of PRBs of the third downlink physical resource block (/ { (10ms subframe cell total downlink PRB number) × 100 }. Where 100 of the denominator indicates the number of radio frames within 1 s.
And the current utilization rate of the uplink physical resource block PRB of the cell is equal to the number of the uplink third physical resource block PRB plus 100%/(the total number of the uplink available PRBs). When the MAC calculates the total number of the uplink available PRBs, the PRB resources occupied by the statically allocated PUCCH and the PRB resources occupied by the dynamically allocated PUCCH can be eliminated.
generally, the usage of the downlink physical resource block PRB is far greater than that of the uplink physical resource block PRB, so in this embodiment of the present application, whether a network congestion situation occurs in the current cell can be determined by using the utilization rate of the downlink physical resource block PRB.
In a specific implementation, it may be determined whether the utilization rate of the PRB exceeds a first preset threshold, and if so, step 205 may be executed to obtain load information of an adjacent target cell to determine whether to perform migration processing on too many users. Those skilled in the art may determine the size of the first preset threshold according to the actual network bearer condition of the current cell, which is not specifically limited in this application.
in the embodiment of the application, for hierarchical cells in different base stations, load information interaction between the cells can be completed through an X2 interface, and for load information between hierarchical cells located in the same base station, the load information interaction between the hierarchical cells can be realized by calling an internal function without using an X2 interface. The X2 interface is an interface between e-nodebs, supporting direct transmission of data and signaling. The e-nodebs are interconnected through an X2 interface to form a mesh network.
In a specific implementation, when a load of a current cell exceeds an early warning threshold, an RRM (Radio resource management) may notify an AP to acquire load information of a neighboring cell, and a neighboring cell that receives a request message periodically reports the load information of the current cell according to an indication in the request message.
In a preferred embodiment of the present application, the step of adjusting the load of the current cell according to the load information of the target cell may specifically include the following sub-steps:
substep 2061, determining whether the target cell supports the resource load type of the current cell;
in this embodiment of the present application, after the current cell sends the request message in the target cell, the target cell may feed back information including its resource load type to the current cell to determine whether the target cell supports the resource load type of the current cell, and if so, may continue to perform substep 2062.
Substep 2062, determining whether the physical resource block PRB utilization rate of the target cell exceeds a second preset threshold;
in this embodiment of the present application, the second preset threshold is a threshold corresponding to a physical resource block PRB utilization rate of the target cell. And if the Physical Resource Block (PRB) utilization rate of the target cell does not exceed the threshold value, the target cell can accept user migration of other cells.
It is noted that if the target cell only partially supports the resource load type requested by the source cell, only migration of users of the corresponding type can be accepted.
Substep 2063, migrating the user of the current cell to the target cell.
In the embodiment of the application, before the user of the current cell is migrated to the target cell, whether the target cell supports the resource load type of the current cell can be further judged, so that the user migration is more targeted and efficient.
It should be noted that, for simplicity of description, the method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the embodiments are not limited by the order of acts described, as some steps may occur in other orders or concurrently depending on the embodiments. Further, those skilled in the art will also appreciate that the embodiments described in the specification are presently preferred and that no particular act is required of the embodiments of the application.
